获取：“尝试获取非对象的属性”时尝试访问对象数组中的值

Question

So from a Get request I get back a response in this structure:

{
  "chromeosdevices" : [
     {
         "somekey" : "somevalue",
         "annotatedUser" : "annotatedUserValue",
         "activeTimeRanges" : [
             {
                 "date" : "dateValue",
                 "activeTime" : "activeTimeValue"
             }
          ],
       "somekey" : "somevalue",
      },
   ]
}

How can I access both DateValue and ActiveTimeValue?

I have tried it with this code:

$dec = json_decode($response);
$filteredResults= array();
if (! empty($dec->chromeosdevices)) {
    foreach ($dec->chromeosdevices as $chromeosdevice) {
        $user['annotatedUser'] = $chromeosdevice->annotatedUser;
        $user['activeTimeRanges_date'] = $chromeosdevice->activeTimeRanges->date;
        $user['activeTimeRanges_activeTime'] = $chromeosdevice->activeTimeRanges -> activeTime;
        $filteredResults[] = $user;
    }
}
echo '<pre>';print_r($filteredResults);echo '</pre>';

However, I only get back the annotatedUser, but not the date and active time. Why is that?

Answer 1

As it is another object in an array use $chromeosdevice->activeTimeRanges[0]->date;

Answer 2

That is in an array so maybe another loop would be the safest way to deal with this

$dec = json_decode($response);
$filteredResults= array();
if (! empty($dec->chromeosdevices)) {
    foreach ($dec->chromeosdevices as $chromeosdevice) {
        $user = [];     // init and remove last loops info
        $user['annotatedUser'] = $chromeosdevice->annotatedUser;
        foreach ($chromeosdevice->activeTimeRanges as $tr) {
            $user['activeTimeRanges_date'][]       = $tr->date;
            $user['activeTimeRanges_activeTime'][] = $tr->activeTime;
        }
        $filteredResults[] = $user;
    }
}
echo '<pre>';print_r($filteredResults);echo '</pre>';
